Formation of the solar system and differentiation of Earth
{"Image DocumentName": "Formation of the solar system and differentiation of Earth", "Image ImageDescription": "Hypotheses must satisfy observations: planets orbit sun in one direction, axes of rotation nearly perpendicular to orbit, most planets rotate in same direction as orbit about sun, >99% solar system mass in sun, ~99% solar system angular momentum in planets. Inner Terrestrial - Mercury, Venus, Earth, Mars. Outer Jovian - Jupiter, Saturn, Uranus, Neptune, Pluto? Terrestrial \u2013 dense, rocky, >3 g cm3, Mg, Fe, Si, K, Ca, metals combined with O. Jovian - gassy <~1.5 g cm3, ice, H, He, CH4 methane CO2.
